The feeding system includes the steps of measuring and weighing bulk materials, controlling the feeding quantity and mixing, which is often used by the computer with automatic batching algorithm software as the control system of its automatic batching. Adopting master-slave structure, connecting multiple single-chip microcomputers into a powerful system, it can be applied to large concrete batching plant, and the materials to be batched at the same time can be as many as 9 to 12 kinds.

The mechanical equipment part of the metering and batching control system includes feeding station, feeding device, batching silo and so on. Measuring automatic Batching system according to the process formula to determine the raw and auxiliary materials, raw and auxiliary materials for material identification; measuring automatic weighing and batching system of the main raw and auxiliary materials, respectively, according to the varieties and quantities required by the operating plan, measuring automatic batching system through the dust-free feeding station directly into the storage silo, metering and batching system through the elevator to move to the batching station, or raw and auxiliary materials into the dust-free feeding station, metering and Weighing system through the vacuum The metering and weighing system is delivered by vacuum conveyor to the metering and weighing system fixed in the batching station.

Hardware part of the production process microcomputer weighing control system hardware generally consists of computer mainframe, interface circuits, conventional peripheral equipment and central operation console. Automatically complete the analysis, calculation and other processing, and then the results of processing and the corresponding control decision output, timely indication of the process conditions and control objects to the control command.

Measurement system in the work, the computer constantly input a variety of peripherals and production site equipment, a variety of information, parameters, by the host quickly processed and the results of timely delivery to the output device for display, alarm or print records, or output instructions to control the operation of field equipment.

Using the bus structure of the microcomputer automation system, the host and the interface is connected through the system bus, the system bus, including the address bus, data bus and control bus, a bus is actually a bunch of wires composed of information public circulation line. Bus structure facilitates the expansion of the system by hooking up more memory and interface circuits on it, and also improves the reliability of the whole system.

Conventional dosing devices Conventional external devices refer to a class of commonly used input and output devices and external memory. The role of input and output devices is to serve as a human (operator) and a machine (computer) "dialog" tool. External memory increases the capacity of the system. A control system to configure how many peripherals need to be determined on a case-by-case basis.

Central operating console central operating console to the computer, the outer ring equipment and the controlled object link. Mechanical production process control system of the central operating console is also equipped with an analog display reflecting the actual working state of the production process. The central operation console is usually equipped with a variety of primary instrumentation instructions, ltd seven-segment digital display, the controlled system production process display, a variety of sound, light alarm devices and manual control switches, buttons and so on. Relay cabinet (strong cabinet) can also use appropriate isolation measures with the central operating console as one. Together with the standard keyboard and crt monitor in the conventional external equipment, it constitutes a complete control system command and monitoring center.
